These are the steps to make an atom.
Step 1 – Gather information
First, you’ll need information about your element. Visit the Periodic Table of Elements
Click on the element you wish to select. You can also select your element directly from the an Alphabetical listing
To find the atomic numbers of your element, use the Table of Elements
the atomic weight. The atomic number is located in the upper left corner, while the atomic weight is located at the bottom. Krypton
Step 2 – The number of protons is…
The number of protons found in an element’s atom is called the atomic number. Krypton’s Atomic Number is 36. This means that an atom made of krypton contains 36 protons in its nuclear.
It is interesting to note that each atom of krypton has 36 protons. An atom that doesn’t contain 36 protons cannot be a krypton atom. A different element is created by adding or subtracting protons from an atom’s nucleus. One proton removed from an atom krypton will create an atom bromine.
Step 3 – The number of electrons is…
Atoms are defined as having no overall electrical charge. This means that the positively charged protons must balance out the negatively charged electrons. Atoms should have equal amounts of protons and electrons. An atom of krypton, for example, must have 36 electrons because it has 36 protons.
The arrangement of electrons around atoms is special. You can learn how electrons are organized around atoms in a special way by looking at the How to read an electron configuration table.
An atom can either gain or lose electrons. This is what we call an ion. An ion is an electrically charged atom. The net charge of an atom is not affected by adding or subtracting electrons.
A kryptonion is formed when an electron is removed from an atom krypton. This is often written as Kr+
. This is a positively charged sign. Because a negatively charged electron was taken from the atom, it is positively charged. The 36 positively charged protons outnumbered the 35 electrons, giving rise to a charge of +1.
Step 4 – The number of neutrons is…
The atomic weight simply measures the number of particles contained in an atom’s nucleus. It is not as simple as that. In reality, the atomic weight is a weighted average from all naturally occurring isotopes.
a relative weight of an element to carbon-12. That was confusing. Doesn’t matter. The mass number is all you need. The Table of Elements doesn’t list the mass number. To find the mass number, you just need to round the atomic weigh to the nearest whole number. Krypton’s mass is 84, since its atomic weigh, 83.80, has been rounded up to 84.
The mass number refers to the count of particles within an atom’s nucleus. The nucleus is important.
is composed of protons, neutrons. If we wish, we can also write:
Mass Number = (Number Protons + (Number Neutrons).
This equation is for krypton:
84 = (Number Of Protons) + (+Number Of Neutrons).
We could easily figure out how many neutrons krypton contains if we knew how many protons it had. Let’s not forget, we know how many protons Krypton has! That was done in Step 2. The number of protons found in krypton is called the atomic number (36). This equation gives us:
84 = 36 + (Number Of Neutrons).
What is 36 times 36? You probably meant 48. This is the number neutrons in an Atom of Krypton.
It is interesting to note that adding or subtracting neutrons to an atom doesn’t create a new element. It creates an element that is heavier or lighter. These are isotopes.
Most elements are made up of a mix of several isotopes.
If you were to take atoms of Krypton and count how many neutrons they had, you’d find that the majority would have 48, 47, 50, 46, 46, 44, 44, 44, 42, and 42, respectively. Because krypton is made up six different isotopes, you would have different numbers of neutrons.
Number of protons = Atomic number
Number of Electrons = Number Protons = Atomic number
Number of Neutrons = Atomic Number – Mass Number
Number of protons = Atomic number = 36
Number of Electrons = Number Protons = Atomic number = 36
Number of Neutrons = Atomic Number – Mass Number = 84-36 = 48
I hope you find it useful.
